Make sure your child knows what to do if approached, grabbed, threatened, or abused by a stranger. A child's natural tendency is to see all adults as authority figures unless they've been taught otherwise. If they haven't been taught, their natural tendency is to freeze and comply. If taught they will remember and not freeze or comply but follow their training.

Also beware of any adults/neighbors/friends who take an usually friendly interest in your child and want to do things with them like take them to the store or shopping or buys them lots of things.

Lastly note any sudden behavior changes in your child. Be-aware, they may be afraid to be honest with you and simply try to tell you something they think you will believe, and it may work if you're in denial. If in doubt seek out the help of a professional and do your own research on how child predators act and their tactics.

Some children who tell on their abusers simply aren't believed by their parents and the abusers usually increase the abuse as a punishment for telling. This may result in the child's behavior becoming even more withdrawn/secretive/angry. Again, always remember to seek professional help if you suspect something.
